Ordinal Multicriteria Methods Applied to the Ranking of Naval and Aerial Defense Systems: Two Hierarchical Approaches Based on the Borda Method
Authors: Ana Paula Dos Santos Rubem, Eduardo Siqueira Brick, João Carlos Correia Baptista Soares De Mello
Abstract: The aim of this paper is to enable a wide range of comparisons regarding the relative naval and aerial warfare capabilities of different nations. With this purpose, two ordinal multicriteria methods have been used to rank order the countries comprised in the analysis. The methods applied were the original Borda and its modified version that uses the median to aggregate the criteria. Due to the inherent hierarchy of the criteria structure, it was necessary to develop hierarchical approaches for applying both methods. The results indicate that, although less influenced by irrelevant alternatives, the power of discrimination among alternatives may decrease, when the hierarchical approach builds on the modified Borda method. In the rankings derived from the analysis, the Turkish defense system obtained the first position when the methodology bases on the original Borda method, while Japan is ranked first if the hierarchical approach grounds on the modified version of that method.
